The Lithuania defender injured the joint in last weekend's 3-1 defeat to Dundee United and is likely to miss the rest of the season, starting with the Jambos' Tynecastle meeting with Killie.
Also missing for John McGlynn's men will be Ryan Stevenson, who was handed a three-match ban following his straight red card for a dangerous studs-up tackle on Gary Mackay-Steven in that Tannadice loss.
